Beginning April 2025, Dŵr Cymru Welsh Water customers will see a 27% increase in water bills. The average yearly bill will jump from £503 to £639.
This rise is part of a major funding plan. Over £4 billion will be invested into improving water services and protecting the environment across Wales.
Why Water Bills Are Rising
The main reason behind this 27% increase in water bills is a long-term investment plan. Welsh Water will roll out upgrades between 2025 and 2030.
Of the £4 billion total, around £2.5 billion will go toward environmental projects. These include:
-
Reducing pollution in rivers and seas
-
Modernizing outdated pipes and equipment
-
Improving the overall quality of drinking water
In addition to service upgrades, these projects are expected to create about 2,000 new jobs.
How Wales Compares to the Rest of the UK
This sharp rise in costs isn’t just happening in Wales. Across the UK, water bills are going up.
On average, UK households will see a 26% rise, bringing the typical bill to £603 a year. That’s £123 more than the previous year, or roughly £10 extra each month.
These increases are meant to make up for years of underfunding in the water sector and to meet stricter environmental rules.
Help for Households Struggling with Costs
While a 27% increase in water bills is significant, help is available for those in need.
Welsh Water has set aside £14 million a year for support programs. Currently, about 150,000 customers benefit from these plans.
Over the next five years, Welsh Water plans to invest £73 million into financial support schemes.
Available Support Programs
To ease the burden, Welsh Water offers several support options:
HelpU Tariff
This plan helps low-income families. If you’re receiving means-tested benefits, you may qualify for reduced water bills.
WaterSure Wales Tariff
If you use a water meter, this program caps your yearly bill. It ensures you don’t pay more than a set amount, no matter your usage.
Cymuned Scheme
This scheme supports working households who are still struggling to cover bills. It offers extra help beyond the other programs.
Tips for Saving on Water Bills
There are ways to manage your water costs—even with the new rates coming in.
Contact Welsh Water
If you’re falling behind on payments, get in touch with Welsh Water’s customer care team. They can review your situation and suggest the best support plan.
Consider a Water Meter
Water meters can save money. You’re only charged for what you use. Installation is free, and many customers end up paying less than on a fixed-rate plan.
Final Thoughts
The 27% increase in water bills is a big change, but it’s linked to major upgrades that will improve services for years to come. While this may strain some households, support programs are available.
Don’t wait until the new rates hit—reach out early, explore your options, and take steps to lower your costs wherever possible.
